Variáveis

$ variável global @ variável de instância [a-z] variável local [A-Z] constante

A única exceção são as pseudo-variáveis, parece locais mas são constantes. São só duas, então não tem confusão.

self o objeto em execução no momento nil valor `sem sentido’ (para false, falso)

Núméricas

@x = -100 @ # Fixnum y = 15_000_000 # Bignum z = 10.22 # Float x, y, z = 0×10, 0b10, 010

x => hexadecial
y => binário
z => octal

Strings

a = “Puta que pariu” @ b = “ha” * 5 @ # => hahahahaha c = “#{a}, meu gato pôs um ovo”

Symbols

a = :a r = :rock

Arrays

a = [“zapata”,“zumbi”,“lampião”] b = %w{zapata zumbi lampiao] c = [4,5,6]

Hashes

a = {1 => ‘Mac’, 2 => ‘Linux’, 3 => ’Windows’}

Ranges

x = 1..5 # 1,2,3,4,5 y = 1…5 # 1,2,3,4

Especiais

$! error message $@ position of an error occurrence $_ latest read string by `gets’ $. latest read number of line by interpreter $& latest matched string by the regexep. $1, $2… latest matched string by nth parentheses of regexp. $~ data for latest matche for regexp $= whether or not case-sensitive in string matching $/ input record separator $\ output record separator $0 the name of the ruby scpript file $* command line arguments for the ruby scpript $$ PID for ruby interpreter $? status of the latest executed child process

Métodos

def fala_oi_mal_educado puts “Oi!” end def somador(x,y) x + y end

Loops

5.times { puts “Ruby manda” } 10.times do |i| puts i end i=0 while(i<10) puts i i+=1 end

If

if true puts “Fala garoto!” end x = 5 case x when 1: puts “O x da questão é 1” when 1: puts “O x da questão é 2” when 3..9: puts “O x da questão está entre 3 e 9” else: "X-Frango

Classes

class Carro def initializer end def buzinar puts “pééééééééééé” end end

Herança

class Passaro def voar puts “batendo asa e voando!” end end class Pinguim < Passaro def voar fail “pinguim nao voa” end end ticotico = Passaro.new ticotico.fly tux = Pinguim.new tux.fly
